Abstract

The invention provides a special compensator for a maintenance-free pipe rack system. The compensator is located on a compensation mechanism mounting frame at least in the length direction of a pipeline; the compensation mechanism mounting frame is mounted on the ground; two ends of the compensator are respectively connected with an upstream pipe body and a downstream pipe body. The compensator is characterized by comprising an inner movable sleeve, an outer sleeve and an end pipe; the end part of the inner movable sleeve is fixed at the lower middle part in the outer sleeve; the end part of the end pipe is fixedly fitted to the inner wall of the top end of the outer sleeve, thus forming a three-layer sleeve structure. The special compensator for the maintenance-free pipe rack system has the outstanding characteristics of no thrust, large compensation distance, low operation cost and the like, and can meet the urban heating requirement.

Description

technical field

[0001] The invention relates to the technical field of pipeline accessories, in particular to a special compensator for a maintenance-free pipe gallery system. Background technique

[0002] Compensators are also customarily called expansion joints, or expansion joints. It consists of a bellows (an elastic element) that constitutes its main body and accessories such as end pipes, brackets, flanges, and conduits. The structure of the existing sleeve compensator generally includes an inner tube and an outer tube, the inner tube is inserted into the outer tube, a sealing packing is provided between the inner tube and the outer tube, and the ends of the inner tube and the outer tube are connected to the heat pipe. When the hot water pipe expands linearly, the inner and outer pipes move relative to each other to compensate for the linear expansion. However, in the sleeve compensator of the traditional structure, the relative movement between the inner tube and th...

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] The invention discloses a special compensator for a maintenance-free pipe gallery system. In this embodiment of the invention, the pipe gallery system is composed of several pipes installed on a support, and each pipe installed on the support is provided with a compensator at intervals. The compensation amount of the compensator of the present invention is large, and there is no need to set up a group every 40-60m. The compensator is at least positioned on the compensation mechanism installation frame along the length direction of the pipeline, and the compensation mechanism installation frame is installed on the ground, and the two ends of the compensator are respectively connected wit...
